The fireball lasted for several seconds and ended with an atmospheric explosion that was detected by US surveillance satellites. According to CNEOS\u2019s data, the fireball moved with a mean speed of 13.6 km\/s and exploded at an altitude of about 35.5 km (Lat. 31.9\u25e6N; Long. 96.2\u25e6E). Inthis paper we estimate the atmospheric trajectory, the heliocentric orbit and the strewn fields for different mass\/section ratio of the fragments. The trajectory was about from north to south and with low inclination (5\u25e6\u00b12\u25e6) with respect to the local surface. The explosion height appear consistent with a fragmented rockybody and the heliocentric orbit supports an asteroidal origin. The probable strewn field extend between twopoints with coordinates (+31.3\u25e6N; 96.3\u25e6E) and (+30.3\u25e6N; 96.5\u25e6E), for a total area of about 4000 km2. This large extension is a direct consequence of the low inclination of the trajectory. Given the unknown uncertainty of the CNEOS\u2019s data, these results should be taken with caution.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Albino Carbognani manuscript submitted to EPJPlus Update (9 March): manuscript v2 submitted to EPJPlus PDF (OPEN ACCESS) Update (2 June 2021): The European Physical Journal Plus volume 136, Article number: 616 (2021)LINK (OPEN ACCESS)PDF (OPEN&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[96],"tags":[880,118,4466,98,141,1301],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/25622"}],"collection":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=25622"}],"version-history":[{"count":5,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/25622\/revisions"}],"predecessor-version":[{"id":27969,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/25622\/revisions\/27969"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=25622"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=25622"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=25622"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
